HOLYOKE – A man who crashed into a car while riding a dirt bike suffered serious injuries and remains in critical condition Sunday.

Perfecto Davila was riding the motorcycle at about 6:30 p.m., Saturday when he collided head-on with a car at the corner of Center and Mosher streets, said Police Sgt. Isaias Cruz, supervisor of the traffic department.

Davila, whose age and address was not available, was originally taken to Baystate Medical Center but was later transferred to Hartford Hospita. The driver of the car was not injured but his Honda was heavily damaged,

“Through our investigation it was learned that the operator of the bike, Perfecto Davila, was operating the dirt bike at high speeds, negligently and recklessly while also performing a wheelie,” Cruz said in a written statement.

Cruz said he went through the stop sign and collided with the Honda. Davila was not wearing a helmet.

It is against Massachusetts general laws to operate a dirt bike on a public way, Police Sgt. Kevin Thomas said.

Police are investigating the theft of the dirt bike at the same time, Cruz said.

“While officers and medical staff were attending to Mr. Davila’s injuries someone dragged the dirt bike from the scene and hid the bike behind a shed at a location in close proximity,” Cruz said.

A witness helped police find the bike. Police towed the bike, which is evidence in the accident, from the scene, he said.

The investigation is continuing. No charges will be filed in the accident or the theft of the bike until the investigation is completed, Cruz said.
